If you have a bunch of mental models derived from card sort and user interview data from a single user group, is it okay to attempt to form a universal mental model by looking at patterns in the different models and forming decisions based on the overall consensus? Or, is this in violation of this citation from Steven Heim?
Mental models are:
Personal—They are specific to each individual and are not universal concepts that can be appliied generically.
The Resonant Interface, Steven Heim
Note: I never use mental models verbatim in future decision making of site maps and wireframes; intuition and usability testing plays a large part in getting it right.
